    Pure as Running Water: A Constitutional Argument for Utah’s Public Trust Doctrine

    Get PDF
    Water rights in America, particularly in western states, have been a pervasive source of legal contention. The histories of these water rights, and the public trust doctrine more broadly, have created a tremendously complex area of law. This field of law is very old and draws on policy concerns stretching back to 100 B.C., overlapping federal and state powers and precedents, and what can only be described as one of the longest games of jurisprudential telephone in existence. As a result, anyone seeking to challenge a state statute, court opinion, or regulation, which they believe impermissibly restricts the public’s right to use the waters, has a big job ahead of them. The party must take on the daunting task of organizing hundreds of years of law into a coherent argument and accounting for every nuance which may lurk in a myriad of state and federal opinions published on the issue

    Felix v. Sero : Brief of Petitioner on Writ of Certiorari to the Utah Supreme Court

    Best Brief in the 2018 Traynor Moot Court Competition. Drafted by Jen Joslin and Brandon Fuller, S.J. Quinney College of Law. This case turns on the great import of protecting and preserving the best interests of children. There are two questions for this Court to determine: (1) the extent to which a parent’s right to travel should influence a custody determination, and (2) the extent to which one parent may avoid paying a share of childcare expenses by asserting an equitable defense of laches. Though both questions implicate the rights and interests of the parents, this Court’s holding should come down to the best interests of the children

    Finding CCA groups and graphs algorithmically

    Get PDF
    Given a group G, any subset C of G\{e} induces a Cayley graph, Cay(G,C). The set C also induces a natural edge-colouring of this graph. All affine automorphisms of the Cayley graph preserve this edge-colouring. A Cayley graph Cay(G,C) has the Cayley Colour Automorphism Property (is CCA), if all its colour-preserving automorphisms are affine. A group G is CCA if every connected Cayley graph on G is CCA. The goal of this thesis is to classify all groups of ‘small’ order to determine if they are CCA. In order to do this, we have developed two main algorithms that are the new contributions of this thesis. One algorithm finds all minimal generating sets for any group. The other algorithm uses this to test whether or not a group is CCA. These algorithms can also be used to determine whether or not a given Cayley graph is CCA.NSERC Canada Graduate Sholarships-Master's Program PIMS-Alberta Graduate Excellence Fellowshi

    Comparison of Machine-Learning and Deep-Learning Methods for the Prediction of Osteoradionecrosis Resulting From Head and Neck Cancer Radiation Therapy

    PURPOSE: Deep-learning (DL) techniques have been successful in disease-prediction tasks and could improve the prediction of mandible osteoradionecrosis (ORN) resulting from head and neck cancer (HNC) radiation therapy. In this study, we retrospectively compared the performance of DL algorithms and traditional machine-learning (ML) techniques to predict mandible ORN binary outcome in an extensive cohort of patients with HNC.METHODS AND MATERIALS: Patients who received HNC radiation therapy at the University of Texas MD Anderson Cancer Center from 2005 to 2015 were identified for the ML (n = 1259) and DL (n = 1236) studies. The subjects were followed for ORN development for at least 12 months, with 173 developing ORN and 1086 having no evidence of ORN. The ML models used dose-volume histogram parameters to predict ORN development. These models included logistic regression, random forest, support vector machine, and a random classifier reference. The DL models were based on ResNet, DenseNet, and autoencoder-based architectures. The DL models used each participant's dose cropped to the mandible. The effect of increasing the amount of available training data on the DL models' prediction performance was evaluated by training the DL models using increasing ratios of the original training data.RESULTS: The F1 score for the logistic regression model, the best-performing ML model, was 0.3. The best-performing ResNet, DenseNet, and autoencoder-based models had F1 scores of 0.07, 0.14, and 0.23, respectively, whereas the random classifier's F1 score was 0.17. No performance increase was apparent when we increased the amount of training data available for DL model training.CONCLUSIONS: The ML models had superior performance to their DL counterparts. The lack of improvement in DL performance with increased training data suggests that either more data are needed for appropriate DL model construction or that the image features used in DL models are not suitable for this task.</p

    The first ever anti-football painting: A consideration of the soccer match in John Singer Sargent’s "Gassed"

    Get PDF
    The paper presents a discussion of Gassed, a large oil painting by John Singer Sargent displayed at the Imperial War Museum in London. Completed in 1919, Gassed is the major achievement from Sargent’s commission as an official war artist at the appointment of the British War Memorials Committee during the latter period of World War I. Prominent in the painting is a group of soldiers, blinded by a mustard gas attack, being lead to a casualty clearing station tent. In the distant background of the painting, another group of soldiers can be seen kitted out in football attire playing a match. The significance of this football imagery is our point of enquiry. As our title suggests, some recent interpretations regard the painting as offering critical reflection, from the time, about the symbolic links between sport and war. However, while the painting may certainly be left open to this type of viewer interpretation, archival and secondary resource material research does not support such a critical intention by the artist. Yet, nor is there evidence that Sargent’s intention was the projection of war-heroism. Rather, Sargent’s endeavour to faithfully represent what he observed allows Gassed to be regarded as a visual record of routine activity behind the lines and of football as an aspect of the daily life of British soldiers during the Great War

    Football: a counterpoint to the procession of pain on the Western Front, 1914-1918?

    Get PDF
    In this article, three artworks of the First World War containing images of recreational football are analysed. These three images, In the Wings of the Theatre of War, Artillery Men at Football and Gassed, span the war from its beginning to its conclusion and are discussed in relationship to the development of recreational football in the front-line area, the evolving policies of censorship and propaganda and in consideration of the national mood in Britain. The paper shows how football went from being a spontaneous and improvised pastime in the early stages of the war to a well organized entertainment by war’s end. The images demonstrate how the war was portrayed as a temporary affair by a confident nation in 1914 to a more resigned acceptance of a semi-permanent event to be endured by 1918; however, all three artworks show that the sporting spirit, and hence the fighting spirit, of the British soldier was intact
